When human civ eventually sends robotic probes to other star systems, we would say hello and start interacting with any alien life (like we do with species on Earth (think David Attenborough)). We wouldn't send probes for silent scanning only.
So, alien probes having visited us is unlikely.
A message to anyone who cares for physics and cosmology and logic:
All the fundamental constants cohere, even 13.8 billion years.
In view of this Big Coincidence (an iteration of Dirac's large numbers hypothesis), What if 13.8 billion years is a constant โ and not an age?
What if 13.8 Gy isn't an age, and what if the universe doesn't have an age?
Either
[13.8 Gy is an age AND the Big Bang Theory is accurate AND this Big Coincidence does not hold or it does with h, c, or proton mass changing]
xor
[13.8 Gy is a constant AND the Big Bang Theory is inaccurate AND the physical constants are indeed constants and this Big Coincidence holds].
Logically, it's one xor the other.
How can one check the validity of the Big Bang Theory? Compare its predictions of the contents of the far universe to what telescopes actually observe. What is observed? Highly developed galaxies. Is that what Big Bang Theory predicted? No.
What next? What is the alternative? Debug the stack of claims. Find the bug and fix the bug. What is the bug? The false redshift explanation: that all galaxies recede or space expands. What is reality?: All galaxies are not receding. Space is not expanding. The redshift is merely and purely photons losing energy as they travel. How? At a rate modeled by E_t / E_0 = e^(-Ht), H being 1/(13.8 Gy).
13.8 billion years is not an age.
It's a constant in the function that models the redshift.
@JohnCarreyrou There is someone who fits the Nakamoto profile better. Also a British-American personality, in his 50s, fascinated with Japan, connected to the Cypherpunks, proficient in C++, obsessed with digital money: Elon Musk.

Despite the absurdity on the face of it, there are a number of things in common between Satoshi Nakamoto (author of the Bitcoin whitepaper and code), and @elonmusk.

@dylfreed@JohnCarreyrou So that section is about the Nakamoto-Back emails, which were private. I am raising the point about the citation. The citation was public! You believe Nakamoto-as-Back would out himself on day one of using his pseudonym?
